This invention relates to radio receiving sets and has for its objects to insulate the cabinet structure containing the radio apparatus against vibration and to accomplish this with a simple practical commercial form of construction, readily applicable to existing radio apparatus and further of such a foi-m as not to mar the generally artistic appearance of the modern radio receiving cabinet. n.

In the drawing` accompanying and forming part of the specification, several different embodiments of the invention are illustrated, but it is to be understood that the structure may be further modified without departure from the true spirit and broad scope of the invention.

Fig. 1 in the drawing is a front elevation of a radio cabinet having the present improvements incorporated therein; Fig. 2 is an enlarged front elevation and part broken sectional View of the cushioned leg construction of the cabinet; Fig. v3 is a detail sectional view as on the plane of line 3-3 of Fig. 2;

25 Fig. 4 is a broken sectional detail of a slight modification in the structure ofthe upper leg cushion; Fig. 5 is a cross-sectional detail as on lines 5 5 of Figs. 2 and 4; Fig. 6 is a broken sectional detail 0I" another form of 0 the lower leg cushion; Figs. 7 and 8 are broken sectional details of base cushions similar to those shown in Figs. 1 and 2; Fig. 9 is a similar enlarged view of the form of base cushion shown in Fig. 6.

The cabinet containing the radio apparatus is indicated generally at and it should be understood that the same may be of any usual or special construction and of the console type shown, the table type of cabinet, or any other style.

Interposed between the cabinet and its support, whether the latter be a floor, table or stand for instance, are cushioned feet which absorb and prevent transmission of vibrations to the cabinet proper.

In the illustration, the cushioned supports are in the form of legs 11 having cushioned sockets in the cabinet base, cushioned intermediate portions and base cushions at the floor.

-post andv the socket formed inthe The cushion sockets for the legs are shown in Figs. 2, 4 and 5 as oversize seats 12 for the cylindrical upper ends 13 of the'legs or corner posts, said seats having grooves 14: therein receiving longitudinal'strips 15 of rubber or other non-microphonic transmitting, cushioning material, "whichA project from the grooves into yielding engagement with the cylindrical portion of thelpos't.y As shown particularly in Fig. 5, these'r'ubb'er strips may be widened at their inner portions, somewhat in T-form to grip the post and positively prevent contact' between "the Corner structure 16 of the cabinet. A pad or pads 1T of rubber or other suitable vibration absorbing material may be placed inthe socket to take the end thrust of the postl This construction enables the post to vibrate in the ing such vibrations to the cabinet.

If. it is desired to shield or hide the telescopic mounting of the post, a construction like that shown in igs. 1 and 2 'may be adopted Where an ornamental flange 18 on the cabinet comes down over a lshouldered portion 19 on the post out of Contact,v so that there' can be no transmission of vibration from one solid portion to another. i l' The intermediate portion 'of the leg o r post is shown cushioned in Figs.'3 and 6 by making the post with relatively telescopicsecti'ohs 20, 21, free of Vv,Contact with each 'other and hollowed to contain af. cushioning spring `22, which latter Ais encased by a flexible'sleeve 23 of rubber or the like to keep the leg sectionsaligned and outof mechanical contact. Pads of'cushion material 24 take the end thrust of thev sustaining'spring, and if desired, va rod 25 may be placed within the spring to aid in aligning the leg sections.

Additional cushioning effect is obtained in the illustration by employing a base 'cushion for each leg made up of discs 2 6 of suitable sustaining 'materiah such as wood, hard rubber, bakelite or the like, supe'rpo'sed one on theother with interposed pads vor rings 27'of rubber, felt or other non-'microphonic transmitting, cushioning materiah'sit' bein noted in this instance also thatthe solid socket in various directions without im'partp which thereupon position the membersV laterally one with respect to. the other. In Fig. 8, the discs are made one sufficiently smaller than the other to avoid contact, andif desired, the pads 27 may be secured by adhesive or the like to the adjoining discs, so as to position the latter' against possibility of contact. One or a number of the discs may be employed and the lowermost disc may have one of the cushions 27 on the underside of the same for immediate contact with the Hoor as in Figs. 7 and 8.

In some localities, it is desirable tovcushion the cabinet supports at the top, the bottom and intermediate, as illustrated, but in quieter locations where there are less vibrations, it may be suflicient to employ only one or two of the vibration insulators. In each form of insulator, a non-microphonic transmitting, support isv provided, which prevents transmission of vibrations and holds the relatively movable parts separated against mechanical contact. The rubber pads also have an electrical insulating effect, which is of importance where the supports for the cabinet are of a metallic nature. 1

The invention is of simple construction, durable to last the life of the cabinet and can be inexpensively made and applied to radio cabinets, without detract-ing in any way from the general appearance of the cabinet.

The base or Hoor cushions when made up of superimposed discs of successivelysmaller size have an ornamental pyramidal appearance and may be of square, angular, circular or other outline to provide different ornamental effects.

Whatis claimed is: 'K

1. In combination with a radio cabinet,

. supports therefor, comprising superposed discs pyramided one on top of the other and of successivelyy smaller sizes with pads of nonmicrophonic transmitting, cushioning material between adjacent discs, said pads being interlocked in opposing faces of adjoining discs to stabilize the multiple cushioned structure againstV lateral displacement.

2. As a new article of manufacture, a. support for radio cabinets comprising discs of relatively hard material, said discs being of different sizes and having cavities in opposite faces of the same and cushions of softer material proportioned to fit in said cavities and to hold the discs sepa-rated when pyramided one on top of the other.

3. AS a new article of manufacture, a radio cabinetA supporting disc of relatively hard material having cavities in opposite faces of j the same and cushions of softer material tting in said cavities and projecting beyond the surface of the disc.

4, As a new article of manufacture, a support for radio cabinets comprising superposed discs pyramided one on top of the other and ofy successively smaller sizes, with annuli of non-microphonic transmitting, cushioning material of successivelyr smaller sizes between adjacent discs and all secured together in assembled pyramidal relation by adhesive or t-he like.

5. As a new article of manufacture, a support for radio cabinets comprising discs of relatively hard material and cushioning pads of softer material between said discs, said discs and pads being of successively smaller sizestoward the tcpof the support to constitute a` pyramid having a wide base. for engagement with a floor o-r other support and a smaller top for engagement with the leg of a radio cabinet, said cushioning pads having the vibration cushioning characteristics of annuli of successively smaller sizes toward the top of the support to effect graduated absorption of vibration and adhesive means securing'said discs and pads of successively smaller sizes assembled in the pyramidal relation described.

In testimony whereof, I aiiix my signature.
